I can vouch for drat repos; they have saved me in developing APIs for
packages under development, e.g. rcbc which is only on Github and not on
CRAN. (As Dirk notes, this only applies to Enhances/Suggests dependence.)

(Disclaimer: Author bias here.) Let me vouch for Additional_repositories:
along with packages in Suggests: (you cannot do this for Imports / Depends /
LinkingTo per CRAN Policy). I have recently been relying on it a lot for a
package I (similarly) could not change that frequently at CRAN, and a
'semi-private / semi-public package' providing functionality I expect to be
provided by another package 'eventually'. With the caveat that you need the
Suggests: mechanism and hence _conditional_ use, it works just like CRAN.
In the meantime Additional_repositories: just works. It expands the set of
repos, so all operations relying on standard install.packages() calls (and
that includes using the remotes package to parse dependencies in CI, say)
just work, both at CRAN and in CI.
`drat` simply helps along by making it easier to provide compatible
repositories.
